The curious case of the boy with the ahem bug

Nigel sounds like an old man.

He used to go "ehm, ehm" almost a year ago and it went away. However, in the recent week or so, it has come back with a vengeance. "Ehm, ehm, ehm!!" all day long - it sounds like he either has a frog stuck in his throat or he's been smoking cigarettes behind our back.

Celest is so irritated by it she wants to send him to the doctor.
